Blit*
  • To copy a large array of bits from one part of a computer's memory to another part, particularly when the memory is being used to determine what is shown on a display screen. "The storage allocator picks through the table and copies the good parts up into high memory, and then blits it all back down again. " See bitblt, BLT, dd, cat, blast, snarf. More generally, to perform some operation (such as toggling) on a large array of bits while moving them.
  • Sometimes all-capitalized as `BLIT' an early experimental bit-mapped terminal designed by Rob Pike at Bell Labs, later commercialized as the AT&T 5620. (The folk etymology from `Bell Labs Intelligent Terminal' is incorrect. Its creators liked to claim that "Blit" stood for the Bacon, Lettuce, and Interactive Tomato. )
